MOPS WITH EXTRACTING MECHANISM Filed April 18', 1962 United StatesPatent 3,089,171 MGPS WITH EXTRACTING MECHANISM Peter S. Voshikian,Melrose, Pa, and Thomas S. Vosbihian, Philadelphia, Pa. (both of 20thand Oxford Sta, Philadelphia, Pa.)

Filed Apr. 18, 1962, Ser. No. 183,398 1 Claim. (Cl. 15-119) Mops are nowon the market having a strand type mop head with the extractor in theform of a split ring pivotally supported on a longitudinally movable rodand with cam means to move the extractor downwardly over the mop handleinto aligned position wtih the mop head for the extracting movement ofthe extractor.

The mop handle must have sufficient strength for the mopping operationand it has been found to be desirable to reduce the size of the portionof the mop handle in rear of the mop head by forming such portion of abar of material. This enables one to reduce the width of the slot or gapin the extractor. If this slot or gap is wider than the mop handle,there is a possibility of strands of the mop head passing through theslot :or gap and becoming entangled with the extractor.

The object of this invention is to devise novel gap closing means whichis automatically controlled.

A further object of the invention is to devise a novel construction andarrangement of a cam which moves the gap closure intoits closed positionprior to the extracting stroke of the extractor over the mop head, saidcam also moving the extractor towards the mop handle so that the gapclosure is opened by contact with the mop handle.

Other novel features of construction and advantage will hereinafterappear in the detailed description.

For the purpose of illustrating the invention, we have shown in theaccompanying drawings a preferred embodiment of it which we have foundin practice will give satisfactory and reliable results. It is, however,to be understood that the various instrumentalities of which theinvention consists can be variously arranged and organized, and theinvention is not limited, except by the scope of the appended claim, tothe exact arrangement and organization of these instrumentalities asherein set forth.

FIGURE 1 is a top plan view of a mop having extractor mechanismembodying our invention.

FIGURE 2 is a section on line 2-4; of FIGURE 1.

FIGURE 3 is a sectional detail showing the cam closing the gap closure.

FIGURE 4 is a section on line 4-4 of FIGURE 5.

FIGURE 5 is a front elevation of the extractor partly broken away toshow the gap closure in closed condition and the mop handle in positionto cause the opening of the gap closure.

FIGURE '6 is a view similar to FIGURE 5 but showing the mop handleopening the gap closure.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings.

A strand type mop head 1 is connected with a mop handle .2 having alongitudinal groove -3 into which a pin 4 extends, the pin beingconnected with an extractor handle 5 in the form of a grasping sleeveadapted to be reciprocated on the mop handle. Pivoted to the extractorhandle at 6 is an actuating rod 7 which passes through a hole 8 in aguide 9 mounted on the mop handle. The front end of the rod is pivotedat 10 to spaced lugs or 3,989,1'?! Patented May 14, 1963 "ice arms 11 atthe upper end of an extractor 12 in the form of an elliptically shapedring having a slot or gap 13 opening through its bottom. The inner wallof the ring at both sides of the gap is provided with a groove 14 forthe reception of a gap closure 15. One end of the gap closure is offsetand pivoted at 16 to the extractor at one side of its gap. The upperface of the gap closure is shown as curved to form when the gap closureis in closed position a continuation of the inner wall of the ring. Theopening movement of the gap closure is limited by the contact of itsoffset portion contacting an end wall of the groove 14.

In order that the .gap in the extractor may be narrow the mop handle inrear of the mop head is in the form of a rectangular bar 17. A cam 18mounted on the bar 17 extends over the rear end of the rnop head, andthe rear wall of the cam has a cam face 19' extending downwardly andforwardly in the form of an inclined plane extending above and below thebar 17. The bar 17 is connected with the mop head in any desired mannerand the rear end of the bar is fixed tothe main portion of the mophandle by a fastener 20. The guide 9 is chambered to receive the bar andmain portion of the mop handle, and the guide is aligned on the mophandle by a rib 21 extending into the groove 3 in the mop handle.

In the operation, the gap closure is automatically opened by contactwith the bar 17, and is preferably autornatically closed by the cam 13as will now be explained.

We will assume that the parts have been returned after the extractingstroke of the extractor to the position shown in FIGURES 1 and 2. Theoperator moves the extractor sleeve 5 forwardly together with rod 7 andextractor 12. The lower end of the extractor contacts the cam face 19 tocause the extractor to swing downwardly and the bar 17 will cause thegap closure 15 to move from the position seen in FIGURE 5 to that seenin FIG- URE 6 and the extractor will pass over the bar. The extractor ispassing over the cam 18 and the cam face 19 at its lower portion willpress against the gap closure and positively move it downward intoclosed position. As the extractor proceeds over the cam, the bottom Wallof the cam maintains the gap closure in closed position. The extractoris now in aligned position with the mop head and moves forwardly overthe strands to extract the water therefrom.

On the return or rearward stroke of the extractor after an extractingoperation, the extractor swings upwardly in passing over the mop head,the rod 7 having a clearance in the hole 8 in the guide 9 to permitupward movement of the rod and extractor. The extractor passesrearwardly over the cam 18 and swings downwardly into contact with thebar 17 ready for the next extracting stroke.

The use of the gap closure prevents the mop strands from becomingentangled with the extractor, and also provides a more completesqueezing action.

The gap closure when released by the bar moves downwardly but due todirt being present does not always close and we therefore prefer to havethe cam ensure the closing.

Having thus described our invention, What we claim as new and desire tosecure by Letters Patent is:

A mop, comprising a mop handle and a mop head connected to the forwardend of said mop handle, the forward position of the mop handle in rearof the mop head being in the form of a rectangular bar, a slidablesleeve a) on the mop handle; a rod pivotally connected at one end tosaid sleeve, a guide on the mop handle through which said rod passes, anextractor in the form of a split ring pivotally connected at its upperend with said rod at a point forwardly of the sleeve connection, saidring having a slot at its bottom to permit it to pass over said bar, theinner wall of the ring at opposite sides of the slot being recessed, agap closure pivoted to the ring at one side of the slot extending acrossthe slot to seat in said recess and having its inner face curved to formwhen in closed position a continuation of the inner wall of said ring,and a cam on the handle in rear of the mop head being of sudh a shapethat it causes said extracting ring during its forward extractingmovement tomove downwardly and said bar causes the gap closure to moveinwardly on its pivot and thereafter said cam because of its shape movesthe gap closure into its closed position in its recess prior to itspassage of the ring over the mop head during its forward extractingstroke.
